AI 中文摘要
我们在全息AdS/QCD框架内研究了ρ、ψ和Υ介子的性质，涵盖了它们的真空唯象学和介质内动力学。通过在一个最初为研究热力学函数而开发的模型中重构味道特定的规范动能函数，我们计算了零温下的矢量介子质量谱、衰变常数以及强子真空极化对缪子反常磁矩的贡献。此外，我们评估了热谱函数，以分析热密介质中质量位移、共振展宽以及矢量束缚态的熔化。最后，利用Kubo公式，我们提取了等离子体电导率作为温度和化学势的函数。
英文摘要
We investigate the properties of $ρ$, $ψ$, and $Υ$ mesons within a holographic AdS/QCD framework, capturing both their vacuum phenomenology and in-medium dynamics. By reconstructing flavor-specific gauge kinetic functions within a model originally developed to study thermodynamic functions, we compute the vector-meson mass spectrum, the decay constants and the hadronic vacuum polarization contributions to the anomalous magnetic moment of the muon at zero temperature. Furthermore, we evaluate the thermal spectral functions to analyze mass shifts, resonance broadening, and the melting of vector bound states in a hot and dense medium. Finally, using the Kubo formula, we extract the electrical conductivity of the plasma as a function of temperature and chemical potential.
